Richard Campbell will be presenting to the Calgary .NET User Group on Wednesday, June 27th. Richard is the co-host of .NET Rocks and an awesome speaker. Based out of Vancouver, he haunts our Calgary corner a few times (last time I remember he was at our 2006 Code Camp) so please do try to get out to see him.
I had issues (read:errors) trying to register on the website so you should be able to just show up for registration (I tried seeing where you could contact someone, but their contact page doesn't seem to have any contact info like oh, emails or phone numbers). The event is in the Nexen Centre, located at 800 7th Ave SW. Once you get in, you have to go upstairs to +15 level, then past the Brown Bag (a sandwich shop), then over a walking bridge to the conference centre. It's poorly marked, but it's the same place I gave my MOSS 2007 presentation if anyone was paying attention. See you there!
